DETAILED DESCRIPTION
[0030] As will be appreciated by one skilled in the art, aspects of
the embodiments may be embodied as a system, apparatus, method, or
program product. Accordingly, embodiments may take the form of an
entirely hardware embodiment, an entirely software embodiment
(including firmware, resident software, micro-code, etc.) or an
embodiment combining software and hardware aspects that may all
generally be referred to herein as a "circuit," "module" or
"system." Furthermore, embodiments may take the form of a program
product embodied in one or more computer readable storage devices
storing machine readable code, computer readable code, and/or
program code, referred hereafter as code. The storage devices may
be tangible, non-transitory, and/or non-transmission. The storage
devices may not embody signals. In a certain embodiment, the
storage devices only employ signals for accessing code.
[0031] Certain of the functional units described in this
specification may be labeled as modules, in order to more
particularly emphasize their implementation independence. For
example, a module may be implemented as a hardware circuit
comprising custom very-large-scale integration ("VLSI") circuits or
gate arrays, off-the-shelf semiconductors such as logic chips,
transistors, or other discrete components. A module may also be
implemented in programmable hardware devices such as field
programmable gate arrays, programmable array logic, programmable
logic devices or the like.
[0032] Modules may also be implemented in code and/or software for
execution by various types of processors. An identified module of
code may, for instance, include one or more physical or logical
blocks of executable code which may, for instance, be organized as
an object, procedure, or function. Nevertheless, the executables of
an identified module need not be physically located together, but
may include disparate instructions stored in different locations
which, when joined logically together, include the module and
achieve the stated purpose for the module.
[0033] Indeed, a module of code may be a single instruction, or
many instructions, and may even be distributed over several
different code segments, among different programs, and across
several memory devices. Similarly, operational data may be
identified and illustrated herein within modules, and may be
embodied in any suitable form and organized within any suitable
type of data structure. The operational data may be collected as a
single data set, or may be distributed over different locations
including over different computer readable storage devices. Where a
module or portions of a module are implemented in software, the
software portions are stored on one or more computer readable
storage devices.
[0034] Any combination of one or more computer readable medium may
be utilized. The computer readable medium may be a computer
readable storage medium. The computer readable storage medium may
be a storage device storing the code. The storage device may be,
for example, but not limited to, an electronic, magnetic, optical,
electromagnetic, infrared, holographic, micromechanical, or
semiconductor system, apparatus, or device, or any suitable
combination of the foregoing.
[0035] More specific examples (a non-exhaustive list) of the
storage device would include the following: an electrical
connection having one or more wires, a portable computer diskette,
a hard disk, a random access memory ("RAM"), a read-only memory
("ROM"), an erasable programmable read-only memory ("EPROM" or
Flash memory), a portable compact disc read-only memory ("CD-ROM"),
an optical storage device, a magnetic storage device, or any
suitable combination of the foregoing. In the context of this
document, a computer readable storage medium may be any tangible
medium that can contain, or store a program for use by or in
connection with an instruction execution system, apparatus, or
device.
[0036] Code for carrying out operations for embodiments may be any
number of lines and may be written in any combination of one or
more programming languages including an object oriented programming
language such as Python, Ruby, Java, Smalltalk, C++, or the like,
and conventional procedural programming languages, such as the "C"
programming language, or the like, and/or machine languages such as
assembly languages. The code may execute entirely on the user's
computer, partly on the user's computer, as a stand-alone software
package, partly on the user's computer and partly on a remote
computer or entirely on the remote computer or server. In the
latter scenario, the remote computer may be connected to the user's
computer through any type of network, including a local area
network ("LAN") or a wide area network ("WAN"), or the connection
may be made to an external computer (for example, through the
Internet using an Internet Service Provider).
[0037] Reference throughout this specification to "one embodiment,"
"an embodiment," or similar language means that a particular
feature, structure, or characteristic described in connection with
the embodiment is included in at least one embodiment. Thus,
appearances of the phrases "in one embodiment," "in an embodiment,"
and similar language throughout this specification may, but do not
necessarily, all refer to the same embodiment, but mean "one or
more but not all embodiments" unless expressly specified otherwise.
The terms "including," "comprising," "having," and variations
thereof mean "including but not limited to," unless expressly
specified otherwise. An enumerated listing of items does not imply
that any or all of the items are mutually exclusive, unless
expressly specified otherwise. The terms "a," "an," and "the" also
refer to "one or more" unless expressly specified otherwise.
[0038] Furthermore, the described features, structures, or
characteristics of the embodiments may be combined in any suitable
manner. In the following description, numerous specific details are
provided, such as examples of programming, software modules, user
selections, network transactions, database queries, database
structures, hardware modules, hardware circuits, hardware chips,
etc., to provide a thorough understanding of embodiments. One
skilled in the relevant art will recognize, however, that
embodiments may be practiced without one or more of the specific
details, or with other methods, components, materials, and so
forth. In other instances, well-known structures, materials, or
operations are not shown or described in detail to avoid obscuring
aspects of an embodiment.
[0039] Aspects of the embodiments are described below with
reference to schematic flowchart diagrams and/or schematic block
diagrams of methods, apparatuses, systems, and program products
according to embodiments. It will be understood that each block of
the schematic flowchart diagrams and/or schematic block diagrams,
and combinations of blocks in the schematic flowchart diagrams
and/or schematic block diagrams, can be implemented by code. The
code may be provided to a processor of a general purpose computer,
special purpose computer, or other programmable data processing
apparatus to produce a machine, such that the instructions, which
execute via the processor of the computer or other programmable
data processing apparatus, create means for implementing the
functions/acts specified in the schematic flowchart diagrams and/or
schematic block diagrams block or blocks.
[0040] The code may also be stored in a storage device that can
direct a computer, other programmable data processing apparatus, or
other devices to function in a particular manner, such that the
instructions stored in the storage device produce an article of
manufacture including instructions which implement the function/act
specified in the schematic flowchart diagrams and/or schematic
block diagrams block or blocks.
[0041] The code may also be loaded onto a computer, other
programmable data processing apparatus, or other devices to cause a
series of operational steps to be performed on the computer, other
programmable apparatus or other devices to produce a computer
implemented process such that the code which execute on the
computer or other programmable apparatus provide processes for
implementing the functions/acts specified in the flowchart and/or
block diagram block or blocks.
[0042] The schematic flowchart diagrams and/or schematic block
diagrams in the Figures illustrate the architecture, functionality,
and operation of possible implementations of apparatuses, systems,
methods and program products according to various embodiments. In
this regard, each block in the schematic flowchart diagrams and/or
schematic block diagrams may represent a module, segment, or
portion of code, which includes one or more executable instructions
of the code for implementing the specified logical function(s).
[0043] It should also be noted that, in some alternative
implementations, the functions noted in the block may occur out of
the order noted in the Figures. For example, two blocks shown in
succession may, in fact, be executed substantially concurrently, or
the blocks may sometimes be executed in the reverse order,
depending upon the functionality involved. Other steps and methods
may be conceived that are equivalent in function, logic, or effect
to one or more blocks, or portions thereof, of the illustrated
Figures.
[0044] Although various arrow types and line types may be employed
in the flowchart and/or block diagrams, they are understood not to
limit the scope of the corresponding embodiments. Indeed, some
arrows or other connectors may be used to indicate only the logical
flow of the depicted embodiment. For instance, an arrow may
indicate a waiting or monitoring period of unspecified duration
between enumerated steps of the depicted embodiment. It will also
be noted that each block of the block diagrams and/or flowchart
diagrams, and combinations of blocks in the block diagrams and/or
flowchart diagrams, can be implemented by special purpose
hardware-based systems that perform the specified functions or
acts, or combinations of special purpose hardware and code.
[0045] The description of elements in each figure may refer to
elements of proceeding figures. Like numbers refer to like elements
in all figures, including alternate embodiments of like
elements.
[0046] FIG. 1 depicts an embodiment of a wireless communication
system 100 for information having symbol repetition. In one
embodiment, the wireless communication system 100 includes remote
units 102 and base units 104. Even though a specific number of
remote units 102 and base units 104 are depicted in FIG. 1, one of
skill in the art will recognize that any number of remote units 102
and base units 104 may be included in the wireless communication
system 100.
[0047] In one embodiment, the remote units 102 may include
computing devices, such as desktop computers, laptop computers,
personal digital assistants ("PDAs"), tablet computers, smart
phones, smart televisions (e.g., televisions connected to the
Internet), set-top boxes, game consoles, security systems
(including security cameras), vehicle on-board computers, network
devices (e.g., routers, switches, modems), aerial vehicles, drones,
or the like. In some embodiments, the remote units 102 include
wearable devices, such as smart watches, fitness bands, optical
head-mounted displays, or the like. Moreover, the remote units 102
may be referred to as subscriber units, mobiles, mobile stations,
users, terminals, mobile terminals, fixed terminals, subscriber
stations, UE, user terminals, a device, or by other terminology
used in the art. The remote units 102 may communicate directly with
one or more of the base units 104 via UL communication signals.
[0048] The base units 104 may be distributed over a geographic
region. In certain embodiments, a base unit 104 may also be
referred to as an access point, an access terminal, a base, a base
station, a Node-B, an eNB, a gNB, a Home Node-B, a relay node, a
device, a core network, an aerial server, or by any other
terminology used in the art. The base units 104 are generally part
of a radio access network that includes one or more controllers
communicably coupled to one or more corresponding base units 104.
The radio access network is generally communicably coupled to one
or more core networks, which may be coupled to other networks, like
the Internet and public switched telephone networks, among other
networks. These and other elements of radio access and core
networks are not illustrated but are well known generally by those
having ordinary skill in the art.
[0049] In one implementation, the wireless communication system 100
is compliant with the 3GPP protocol, wherein the base unit 104
transmits using an OFDM modulation scheme on the DL and the remote
units 102 transmit on the UL using a SC-FDMA scheme or an OFDM
scheme. More generally, however, the wireless communication system
100 may implement some other open or proprietary communication
protocol, for example, WiMAX, among other protocols. The present
disclosure is not intended to be limited to the implementation of
any particular wireless communication system architecture or
protocol.
[0050] The base units 104 may serve a number of remote units 102
within a serving area, for example, a cell or a cell sector via a
wireless communication link. The base units 104 transmit DL
communication signals to serve the remote units 102 in the time,
frequency, and/or spatial domain.
[0051] In one embodiment, a base unit 104 may transmit multiple
sets of information. In such an embodiment, each set of information
of the multiple sets of information includes a group of basic
symbols and optional repetition symbols, and the optional
repetition symbols are a repetition of at least part of the group
of basic symbols. Accordingly, a base unit 104 may transmit
information having symbol repetition.
[0052] In one embodiment, a remote unit 102 may receive multiple
sets of information. In such an embodiment, each set of information
of the multiple sets of information includes a group of basic
symbols and optional repetition symbols, and the optional
repetition symbols are a repetition of at least part of the group
of basic symbols. Accordingly, a remote unit 102 may be used for
receiving information having symbol repetition.
[0053] FIG. 2 depicts one embodiment of an apparatus 200 that may
be used for information having symbol repetition. The apparatus 200
includes one embodiment of the remote unit 102. Furthermore, the
remote unit 102 may include a processor 202, a memory 204, an input
device 206, a display 208, a transmitter 210, and a receiver 212.
In some embodiments, the input device 206 and the display 208 are
combined into a single device, such as a touchscreen. In certain
embodiments, the remote unit 102 may not include any input device
206 and/or display 208. In various embodiments, the remote unit 102
may include one or more of the processor 202, the memory 204, the
transmitter 210, and the receiver 212, and may not include the
input device 206 and/or the display 208.
[0054] The processor 202, in one embodiment, may include any known
controller capable of executing computer-readable instructions
and/or capable of performing logical operations. For example, the
processor 202 may be a microcontroller, a microprocessor, a central
processing unit ("CPU"), a graphics processing unit ("GPU"), an
auxiliary processing unit, a field programmable gate array
("FPGA"), or similar programmable controller. In some embodiments,
the processor 202 executes instructions stored in the memory 204 to
perform the methods and routines described herein. The processor
202 is communicatively coupled to the memory 204, the input device
206, the display 208, the transmitter 210, and the receiver
212.
[0055] The memory 204, in one embodiment, is a computer readable
storage medium. In some embodiments, the memory 204 includes
volatile computer storage media. For example, the memory 204 may

408, a fifth block 410, a sixth block 412, a seventh block 414, and
an eighth block 416.
[0063] FIG. 5 is a schematic block diagram illustrating one
embodiment of a block 500 of the master information block 400 of
FIG. 4. The block 500 may represent any of the first block 402, the

frame 504, a third frame 506, a fourth frame 508, a fifth frame
510, a sixth frame 512, a seventh frame 514, and an eighth frame
516.
[0064] FIG. 6 is a schematic block diagram illustrating one
embodiment of a frame 600 of the block 500 of FIG. 5. The frame 600
may represent any of the first frame 502, the second frame 504, the
third frame 506, the fourth frame 508, the fifth frame 510, the
sixth frame 512, the seventh frame 514, and/or the eighth frame 516
of the block 500. In various embodiments, the frame 600 includes 10
subframes as illustrated (e.g., subframes 0, 1, 2, 3, 4, 5, 6, 7,
8, and 9). In some embodiments, the frame 600 spans a 10 ms time
period and each of the subframes spans a 1 ms time period.
[0065] FIG. 7 is a schematic block diagram illustrating one
embodiment of a subframe 700 of the frame 600 of FIG. 6. The
subframe 700 may represent any of the subframes 0, 1, 2, 3, 4, 5,
6, 7, 8, and/or 9 of the frame 600. In one embodiment, the subframe
700 represents subframe 1. In another embodiment, the subframe 700
represents either subframe 0, 5, or 6. The subframe 700 includes
symbols 702 (e.g., OFDM symbols). As illustrated, the symbols 702
are individually labeled as symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
10, 11, 12, and 13. In certain embodiments, the subframe 700
includes a number of subcarriers 704. Specifically, as illustrated,
the subframe 700 includes 12 subcarriers. The symbols 702 include a
group of basic symbols 706 and optional repetition symbols 708. As
used herein, the term symbol as used in the group of basic symbols
706 and the optional repetition symbols 708 refers to an
information symbol or information having a size of a symbol.
Specifically, the group of basic symbols 706 includes symbols 2, 3,
4, 5, 6, 7, and 8. Moreover, the optional repetition symbols 708
include symbols 9, 10, and 11. In one embodiment, symbols 0, 1, 2,
3, 4, 5, 6, 7, 8, 9, 10, and 11 are part of a DwPTS of a TDD
special subframe.
[0066] In certain embodiments, a set of information (e.g., NB-PBCH)
may be mapped to a special subframe (e.g., subframe 1) within the
frame 600 (e.g., a 1 PRB bandwidth having a period of 10 ms). In
such embodiments, the set of information may include the group of
basic symbols 706 (e.g., basic PBCH) and optional repetition
symbols 708 (e.g., additional repetition PBCH). In various
embodiments, a length of the optional repetition symbols 708 may
depend on a DwPTS length of a TDD special subframe. In various
embodiments, a coded MIB-NB (e.g., basic PBCH) may be split into 8
blocks. In such embodiments, the coded MIB-NB may be transmitted in
a first block of the 8 blocks on a subframe 1 of a first frame
using symbols 2 through 8 and repeated in symbols 2 through 8 of
subframe 1 of the next 7 consecutive frames. Furthermore, the coded
MIB-NB may be transmitted in the remaining 7 blocks in the same
manner (e.g., in a subframe 1 of a first frame of the block using
symbols 2 through 8 and repeated in symbols 2 through 8 of subframe
1 of the next 7 consecutive frames) until the whole coded MIB-NB is
transmitted. In some embodiments, symbols are mapped around a
narrowband reference signal ("NRS") and a cell-specific reference
signal ("CRS"). In certain embodiments, two antenna ports may be
used for NRS and 4 antenna ports may be used for CRS.
[0067] In various embodiments, the optional repetition symbols 708
may be determined by: dividing the group of basic symbols 706 into
2 types (e.g., a type 1 symbol with CRS and/or NRS and a type
symbol 2 without CRS and/or NRS); mapping the type 1 symbol in the
optional repetition symbols 708 with CRS and/or NRS (e.g., map the
type 1 symbol to the first symbol with CRS in each of the subframes
within a transmitted block; and map the type 1 symbol to the second
symbol with CRS in each of the subframes within the transmitted
block until all symbols with CRS have mapped type 1 symbols); and
mapping the type 2 symbol in the optional repetition symbols 708
without CRS and/or NRS (e.g., map the type 2 symbol to the first
symbol without CRS in each of the subframes within a transmitted
block; and map the type 2 symbol to the second symbol without CRS
in each of the subframes within the transmitted block until all
symbols without CRS have mapped type 2 symbols).
[0068] One example of determining a mapping for the optional
repetition symbols 708 is illustrated in FIGS. 8 through 15.
[0069] FIG. 8 is a schematic block diagram illustrating one
embodiment of a first subframe 800 of information having symbol
repetition among symbols 802. Although only one subcarrier is
illustrated, there may be up to 12 subcarriers that make a PRB of
the first subframe 800. In the illustrated example, type 1 symbols
are labeled with one of "A," "B," "C," "F," or "G." Moreover, type
2 symbols are labeled with one of "D" or "E." Symbols 2 through 8
include one of each of symbols with "A," "B," "C," "D," "E," "F,"
and "G." In this example, the type 1 symbols (A, B, C, F, G) are
mapped to symbol 9, then symbol 10 in consecutive 8 frames as
illustrated in FIGS. 8 through 15. Moreover, type 2 symbols (D, E)
are mapped to symbol 11 in consecutive 8 frames as illustrated in
FIGS. 8 through 15. In some embodiments, the type 1 symbols (A, B,
C, F, G) may be substantially (e.g., almost) evenly repeated in the
optional repetition symbols 708 within a first block of
NB-PBCH.
[0070] FIG. 9 is a schematic block diagram illustrating one
embodiment of a second subframe 900 of information having symbol
repetition. FIG. 10 is a schematic block diagram illustrating one
embodiment of a third subframe 1000 of information having symbol
repetition. FIG. 11 is a schematic block diagram illustrating one
embodiment of a fourth subframe 1100 of information having symbol
repetition. FIG. 12 is a schematic block diagram illustrating one
embodiment of a fifth subframe 1200 of information having symbol
repetition. FIG. 13 is a schematic block diagram illustrating one
embodiment of a sixth subframe 1300 of information having symbol
repetition. FIG. 14 is a schematic block diagram illustrating one
embodiment of a seventh subframe 1400 of information having symbol
repetition. FIG. 15 is a schematic block diagram illustrating one
embodiment of an eighth subframe 1500 of information having symbol
repetition. Although only one subcarrier is illustrated for
subframes 900, 1000, 1100, 1200, 1300, 1400, and 1500, there may be
up to 12 subcarriers that make a PRB for such subframes.
[0071] FIG. 16 is a schematic flow chart diagram illustrating one
embodiment of a method 1600 for information having symbol
repetition. In some embodiments, the method 1600 is performed by an
apparatus, such as the base unit 104. In certain embodiments, the
method 1600 may be performed by a processor executing program code,
for example, a microcontroller, a microprocessor, a CPU, a GPU, an
auxiliary processing unit, a FPGA, or the like.
[0072] The method 1600 may include transmitting 1602 multiple sets
of information. In such an embodiment, each set of information of
the multiple sets of information includes a group of basic symbols
and optional repetition symbols, and the optional repetition
symbols are a repetition of at least part of the group of basic
symbols.
[0073] In one embodiment, the group of basic symbols is repeated in
a first symbol of the optional repetition symbols of the multiple
sets of information until the first symbol of the optional
repetition symbols of each set of information is filled. For
example, if the basic symbols are "1, 2, 3, 4, 5" and a number of
repetition symbols is 3 so that each set of information includes 8
symbols, and there are four sets of information, then, a first set
of information may be "1, 2, 3, 4, 5, 1, 5, 4," a second set of
information may be "1, 2, 3, 4, 5, 2, 1, 5," a third set of
information may be "1, 2, 3, 4, 5, 3, 2, 1," and a fourth set of
information may be "1, 2, 3, 4, 5, 4, 32."
[0074] In certain embodiments, the group of basic symbols is
repeated in the optional repetition symbols of a set of information
of the multiple sets of information until the set of information is
filled. For example, if the basic symbols are "1, 2, 3, 4, 5" and a
number of repetition symbols is 3 so that each set of information
includes 8 symbols, and there are four sets of information, then, a
first set of information may be "1, 2, 3, 4, 5, 1, 2, 3," a second
set of information may be "1, 2, 3, 4, 5, 4, 5, 1," a third set of
information may be "1, 2, 3, 4, 5, 2, 3, 4," and a fourth set of
information may be "1, 2, 3, 4, 5, 5, 1, 2." As another example, if
the basic symbols are "1, 2, 3, 4, 5" and a number of repetition
symbols is 3 so that each set of information includes 8 symbols
(but a potential maximum number of repetition symbols is 4 and the
repetition pattern is based on the potential maximum number), and
there are four sets of information, then, a first set of
information may be "1, 2, 3, 4, 5, 1, 2, 3" (with a 4 symbol in the
potential repetition symbol slot 4, but not transmitted), a second
set of information may be "1, 2, 3, 4, 5, 5, 1, 2" (with a 3 symbol
in the potential repetition symbol slot 4, but not transmitted), a
third set of information may be "1, 2, 3, 4, 5, 4, 5, 1" (with a 2
symbol in the potential repetition symbol slot 4, but not
transmitted), and a fourth set of information may be "1, 2, 3, 4,
5, 3, 4, 5" (with a 1 symbol in the potential repetition symbol
slot 4, but not transmitted).
[0075] In various embodiments, one or more symbols of the group of
basic symbols are repeated in the optional repetition symbols of
each set of information of the multiple sets of information. For
example, if the basic symbols are "1, 2, 3, 4, 5" and a number of
repetition symbols is 3 so that each set of information includes 8
symbols, and there are four sets of information, then, a first set
of information may be "1, 2, 3, 4, 5, 1, 2, 3," a second set of
information may be "1, 2, 3, 4, 5, 1, 2, 3," a third set of
information may be "1, 2, 3, 4, 5, 1, 2, 3," and a fourth set of
information may be "1, 2, 3, 4, 5, 1, 2, 3."
[0076] In some embodiments, the group of basic symbols is repeated
partially or entirely a number of times among the multiple sets of
information. In one embodiment, the multiple sets of information
include cell broadcast information. In a further embodiment, the
multiple sets of information include system information. In certain
embodiments, a number of symbols of the group of basic symbols is
fixed or preconfigured by a system. In various embodiments, a
number of symbols of the optional repetition symbols ranges from
zero to a positive number and is determined based on a system
configuration. In some embodiments, a number of the multiple sets
of information is fixed or determined based on a system
configuration.
[0077] FIG. 17 is a schematic flow chart diagram illustrating
another embodiment of a method 1700 for information having symbol
repetition. In some embodiments, the method 1700 is performed by an
apparatus, such as the remote unit 102. In certain embodiments, the
method 1700 may be performed by a processor executing program code,
for example, a microcontroller, a microprocessor, a CPU, a GPU, an
auxiliary processing unit, a FPGA, or the like.
[0078] The method 1700 may include receiving 1702 multiple sets of
information. In such an embodiment, each set of information of the
multiple sets of information includes a group of basic symbols and
optional repetition symbols, and the optional repetition symbols
are a repetition of at least part of the group of basic
symbols.
[0079] In one embodiment, the group of basic symbols is repeated in
a first symbol of the optional repetition symbols of the multiple
sets of information until the first symbol of the optional
repetition symbols of each set of information is filled. In certain
embodiments, the group of basic symbols is repeated in the optional
repetition symbols of a set of information of the multiple sets of
information until the set of information is filled.
[0080] In various embodiments, one or more symbols of the group of
basic symbols are repeated in the optional repetition symbols of
each set of information of the multiple sets of information. In
some embodiments, the group of basic symbols is repeated partially
or entirely a number of times among the multiple sets of
information. In one embodiment, the multiple sets of information
include cell broadcast information. In a further embodiment, the
multiple sets of information include system information. In certain
embodiments, a number of symbols of the group of basic symbols is
fixed or preconfigured by a system. In various embodiments, a
number of symbols of the optional repetition symbols ranges from
zero to a positive number and is determined based on a system
configuration. In one embodiment, a number of the multiple sets of
information is fixed or determined based on a system
configuration.
[0081] Embodiments may be practiced in other specific forms. The
described embodiments are to be considered in all respects only as
illustrative and not restrictive. The scope of the invention is,
therefore, indicated by the appended claims rather than by the
foregoing description. All changes which come within the meaning
and range of equivalency of the claims are to be embraced within
their scope.
